Advantages of Velan-Proquip Check Valves over Conventional Swing Checks

REDUCED SIZE WEIGHT COST:The inherent design of the double flapper check valves results in a signifi-cantly reduced weightas compared to the conventional full bodied check

valve.As the valves increase in size the Velan-Proquipvalve will be aslittle as one fifth the weight of the full bodied unit. This results in savings ininitial cost, space, and pipe support element installation.

The two factors that affect pressure dropacross any valve are:1) The unobstructedflow area.2) The energy required to maintain the valve

in the open position.

Specifically, full-bodied swing check valveshave a disc which is hinged at the top withgravity working to keep it in the closed posi-

tion. Flow must provide sufficient energy toovercome this force of gravity and lift the disc.This energy requirement increases dramticallyin larger sizes.Velan-Proquip valves are installed such thatthe flappers are hinged at their sides like adoor. Thus, the effect of gravity is eliminated.Consequently, very little energy is needed toopen the valve and maintain this position,resulting in lower energy costs.

REDUCED LINE SHOCK:To minimize/eliminate line shock, check valves must close asquickly as possible prior to the flow having an opportunity toreverse. As each of the flappers in the Velan-Proquipcheckvalve is only half the size of that of a full bodied check, they

experience reduced fluid drag and can move more quickly to theclosed position.Their swing radius is one half that of the conven-tional check valves.The leading edge distance from open to closedposition is halved, in turn reducing the travel time by 50%.

The reduced weight ofa dual disc valve flapper versus the fullbodied swing check is a major factor in minimizing water hammer.The heavier full bodieddisc has greater momentum when swingingclosed,causing it to slam into the valve seat resulting in severedamage, (in large valve sizes the disc can weigh up to a ton).

For potentially severe applications, Velan-Proquipoffers a hightorsion spring to ensure the valve closes as quickly as possible.

Features of Velan-Proquip Wafer Style Twin Flapper Valves

RETAINERLESS BODY DESIGN:With growing concern over fugitive emissions, andpotential environmental implications, Velan-Proquiphas standardized on a retainerless,fugitive emission design. Alternate designs incorpo-rating threaded or, threaded/seal welded pipe plugretainers have potential for leakage due to improperfield assembly or corrosion at their threads.

RetainerlessVelan-Proquipdesign

LAPPED BODY/FLAPPER SEATS:The heart of each valve is the seat/seal interface.Velan-Proquiputilizes the most updatedmachining methods and equipment to achieve maximum flatness with a fine lapped finish. Theend result being product that easily meets and exceeds test requirements of API 598 for metalseated check valves.

SHOCK BUMPERS:The Velan-Proquipdesign utilizes heavy duty shock bumperson the back ofeach flapper. These bumpers meet when the valve is in the full open position (seeillustration)thus preventing the flappers from striking the stop pin. This arrangementreduces the shock force on the hinges, ensuring internal components have an ex-tended cycle life with minimal wear under the most severe service conditions.

BODY WITH UNINTERRUPTED GASKETSURFACE:

SUPERIOR HINGE DESIGN:In order to eliminate seat wear during the opening cycle, all dual plate checkvalves incorporate clearance between the hinge pin and body bearings, orhinge pin and flapper bore. This allows the plate assembly to lift off the seatprior to flapper rotation preventing the heel of each flapper from scrapingacross the body seat. Competitive products have an oversize bore in theflappers or bearings. This weakness in the form of added clearance permitsthe flappers to move side to side allowing constantrattling 24 hours a day,leading to premature failure.Velan-Proquipfeatures a slot for the hinge pin, allowing it to move only inone axis. Flappers last longer and the useful life of the valve is extended,

Other retainerless designs have an internal retentionmethod incorporating a special key and retainingscrews. These components ecroach on the serratedsealing face area and as well the screws can corrodemaking maintenance difficult. Velan-Proquiputilizes an internal retention method which does notencroach on the gasket sealing surface.
